Design
Introduced in 1994 to replace the 113 series EMUs running on the Sōbu Line (Rapid) and Yokosuka Line, it was the first outer-suburban train type in Japan to feature four pairs of doors per side on car. The basic design was developed from the 209 series commuter EMUs. It replaced all the Yokosuka Line 113 series trains by 1999.
They use Mitsubishi GTO thyristors and VVVF inverters with Mitsubishi MT68 traction motors. Gear ratio is 97:16.
